Questions
Is the file uploaded to convert it?
No. The conversion runs in your browser, and the picture never leaves this device. There is no account and no daily limit.
What happens to a transparent PNG when I convert it to JPEG?
JPEG has no transparency, so the transparent areas are filled with white. Convert to PNG or WebP if you need to keep the transparency.
Why can the converted file be bigger?
PNG stores every pixel without loss, so a photo saved as PNG is often much larger than the same photo as JPEG or WebP. The page shows both sizes so you can compare.
